I used them on a 50 deg F day. It was sunny so I started out without the heat turned on. After a couple hours, my fingers started getting cold as usual. I connected the batteries and set the heat to 75 and may hands warmed up nicely. Rode about 2 hours more and the batteries were still going strong. Curious to see if I can get 8-10 hours as advertised.
